It can be the cause of induction and act as a cause of environmental and allergic diseases such as atopy, and in the case of airborne mold, it can also cause respiratory diseases such as asthma.

이와 같은 곰팡이, 세균 등이 공기 중에 유입되는 것을 방지하려면 실내가 청결하게 유지되고 곰팡이가 자랄 수 있는 습기가 많은 환경이 제거되어야 하는데, 현재의 벽지는 공기 중의 수분을 그대로 머금어서 곰팡이 등이 자랄 수 있는 환경을 제공할 수 있는 문제가 있다.In order to prevent mold and bacteria from entering the air, it is necessary to keep the room clean and remove a humid environment where mold can grow. There is a problem that can provide an environment where there is

또한, 벽지 뿐 아니라 건축 내장재나 콘크리트 등으로부터 발생하는 포름알데히드, 라돈가스 등과 같은 휘발성 유기화합물로 인해, 주거 환경의 질이 저하되는 문제가 있다.In addition, there is a problem in that the quality of the residential environment is deteriorated due to volatile organic compounds such as formaldehyde and radon gas generated from not only wallpaper but also building interior materials and concrete.

위와 같은 유해 물질들을 차단하기 위해 다양한 유해 물질 차단 코팅제들이 사용되고 있으며, 일예로서 한국 등록특허공보 제0613877호(2005. 10. 31. 출원)에서는 물, 수용성 분산제, 수용성 유기 점증제, 첨가제 등의 혼합물에 옥 분말, 이산화티타늄, 석(石) 분말, 세라믹 바인더를 혼합하여 이루어지는 옥 성분을 포함하는 페인트 내장재가 개시되어 있다.To block the above harmful substances, various harmful substance blocking coating agents are used. As an example, in Korean Patent Publication No. 0613877 (filed on Oct. 31, 2005), a mixture of water, a water-soluble dispersant, a water-soluble organic thickener, an additive, etc. There is disclosed a paint interior material comprising a jade component made by mixing the jade powder, titanium dioxide, stone powder, and a ceramic binder.

그러나, 이러한 페인트 내장재는 가격이 고가이며, 페인트 성분 자체에서 휘발성 유기화합물이 발산되어 인체에 악영향을 미칠 수 있다는 문제점이 있다.However, such paint interior materials are expensive, and there is a problem that volatile organic compounds are emitted from the paint component itself, which may adversely affect the human body.

도 1을 참조하면, 먼저 분산기에 수성 아크릴을 투입하여 제1 온도에서 입자를 분산시킨 후(S110 단계), 분산된 수성 아크릴과 수성 실리콘을 제1 온도보다 높은 제2 온도에서 배합하고(S120 단계), 배합된 수성 아크릴과 수성 실리콘에 송진 레진(resin)과 나노카본(nano carbon)를 혼합하여 코팅액을 제조한다(S130 단계).Referring to FIG. 1 , first, aqueous acrylic is put into the disperser to disperse the particles at a first temperature (step S110), and then the dispersed aqueous acrylic and aqueous silicone are mixed at a second temperature higher than the first temperature (step S120). ), a coating solution is prepared by mixing rosin resin and nano carbon with the aqueous acrylic and aqueous silicone blended (step S130).

S110 단계에서, 비드밀(Bead Mill)이나 호모믹서(homomixer) 등과 같은 분산기에 수성 아크릴을 투입한 후에, 투입된 수성 아크릴의 입자를 고루 분산한다.In step S110, after the aqueous acryl is put into a disperser such as a bead mill or a homomixer, the particles of the introduced aqueous acryl are uniformly dispersed.

그 후, 분산된 수성 아크릴이 50℃에서 100cP의 점도를 가질 때 수성 실리콘이 배합될 수 있다.Then, the aqueous silicone can be compounded when the dispersed aqueous acrylic has a viscosity of 100 cP at 50°C.

도 2를 참조하여 S110 단계에서의 분산 과정을 보다 상세히 설명하면, 분산기에 투입된 수성 아크릴을 50℃의 온도에서 분산하여(S111 단계), 분산 점도가 100cP가 되는 경우(S112 단계), 수성 실리콘이 투입된다(S113 단계).When the dispersion process in step S110 is described in more detail with reference to FIG. 2, the aqueous acrylic injected into the disperser is dispersed at a temperature of 50° C. (step S111), and when the dispersion viscosity becomes 100 cP (step S112), the aqueous silicone is input (step S113).
